Modular Port Concentrators (MPCs) provide packet forwarding services. The MPCs are

inserted into a slot in a router. Modular Interface Cards (MICs) provide the physical

interfaces and install into the MPCs. You can install up to two MICs of different media

types on the same MPC as long as the MPC supports those MICs.

A specialized fixed configuration MPC provides higher port density over MICs and combines

packet forwarding and Ethernet interfaces onto a single line card. The fixed configuration

MPC is inserted into a slot in a router and contains no slots for MICs.

MICs receive incoming packets from the network and transmit outgoing packets to the

network. During this process, each MIC performs framing and high-speed signaling for

its media type. Before transmitting outgoing data packets through the MIC interfaces,
